Machine learning algorithms are excellent at answering “yes” or “no” questions. For example, they can scan huge datasets and correctly tell us: Does this credit card transaction look fraudulent? Is there a cat in this photo?
But it’s not only the simple questions – they can also tackle nuanced and complex questions.
Today, machine learning algorithms can detect over 100 types of cancerous tumors more reliably than a trained human eye. Given this impressive accuracy, we started to wonder: what could machine learning tell us about where people live? In cities that are expanding at breathtaking rates and are at risk from natural disasters, could it warn us that a family’s wall might collapse during an earthquake or rooftop blow away during a hurricane?

They play such a pivotal role in addressing global challenges and improving citizen’s lives that
Yet, it is nations that have led the discussions around solutions for a rapidly urbanizing world, leaving the voices of cities to a secondary role.
To highlight and share effective solutions to some of the most pressing challenges of our time, over 30 mayors from around the world will gather at the First Urban 20 Mayors Summit in Buenos Aires, Argentina, October 29-30, 2018. Together, they will provide concrete, experience-based recommendations to the leaders of the G20 countries on what it takes to achieve urban sustainability, inclusion, and prosperity.
As a strategic partner of the summit and the overall Urban 20 (U20) Initiative, the World Bank Group – including the World Bank and the International Finance Corporation (IFC) – is committed to helping global cities bring their expertise, needs, and voices to the center of global discussions on sustainable development. At the summit, the World Bank will present a series of knowledge notes to inform the U20 discussions and promote the exchange of ideas and innovative approaches to complex development issues, including:
- The future of work in cities
- Affordable housing in the world’s cities
- Urban mobility, health and public spaces
- Urban water resilience
In this video, World Bank Senior Director Ede Ijjasz-Vasquez (@Ede_WBG) and Lead Urban Specialist Horacio Terraza (@TerrazaH) talk about the importance of the U20 Initiative, the World Bank’s participation in the First U20 Mayors Summit, and what is next for U20 cities after the summit in Buenos Aires.

Post-disaster assessments changed my life by starting my career in disaster risk management. Three months after arriving in Indonesia as the World Bank’s environment coordinator, the Indian Ocean tsunami and related earthquakes struck Aceh and Nias at the end of 2004. I was asked to pull together the economic evaluation of the disaster’s environmental impact as part of what was then known as a damage-and-loss assessment. Subsequently, the World Bank, United Nations and European Union agreed on a joint approach to crisis response in 2008, including a common methodology for post-disaster needs assessment (PDNA).
Now that we have a decade of experience with this approach, what have we learned and how can we do a better job in the future?
Gender equality is central to ongoing global efforts to reduce extreme poverty and improve livelihoods for all.
Strengthening women’s land tenure security improves their rights and their dignity. Importantly,
Although gains have been made to increase legal protections for women to use, manage, own and inherit land, in practice, women often aren’t able to realize their rights to the land on which they live, work and depend for survival.
In a video blog marking the International Day of Rural Women, World Bank Director Anna Wellenstein and Senior Land Administration Specialist Victoria Stanley discuss three “headlines” one may encounter on women and land:
- Globally, there is an understanding that reducing poverty requires secure land tenure, and that women’s share in that is important.
- Researchers and policymakers don’t have enough gender-disaggregated data at the country level to understand the true scope of the challenge of women’s land rights, but efforts are underway to collect more data and gain a better understanding.
- There are strong pilots and initiatives of women themselves to gain equal access to land and improve tenure security, but now these efforts need to go to scale.
To drive broader development impact and affect lasting change, the World Bank joins global and regional partners – Landesa, Global Land Tool Network (GLTN), UN-Habitat, Habitat for Humanity, and the Huairou Commission – and local women and communities in preparing an advocacy campaign that aims to close the gap between law and practice on women’s land rights.

As you can see in our new report, What a Waste 2.0: A Global Snapshot of Solid Waste Management to 2050,
Poorly managed waste is contaminating the world’s oceans, clogging drains and causing flooding, transmitting diseases, increasing respiratory problems from burning, harming animals that consume waste unknowingly, and affecting economic development such as through tourism.
Without urgent action, these issues will only get worse. Here’s what everyone should know.
Saddled with weak political systems and ravaged by strife, According to the Overseas Development Institute, 58 percent of deaths from disasters between 2004 and 2014 occurred in countries with fragile contexts.
Yet, even as people in fragile, conflict and violence-affected countries struggle to cope with the growing dangers from natural disasters, the international donor community has been slow to respond, explains Thomas Lennartz of the Global Facility for Disaster Reduction and Recovery (GFDRR). Tellingly between 2005 and 2010, for every $100 spent on humanitarian assistance to these countries, only $1.30 was spent on disaster risk management (DRM).
So what can be done to help close this funding gap? In this video from the 2018 Understanding Risk Forum, hosted by GFDRR and the World Bank, Lennartz offers his take – and shares a few insights on GFDRR’s emerging DRM portfolio in fragile, conflict and violence-affected countries.

A paved road can lead to a world of possibilities for small business owners, increasing access to additional markets and suppliers, as well as opportunities to grow their businesses.
The urban infrastructure finance gap
Cities already account for approximately 70-80 percent of the world’s economic growth, and this will only increase as cities continue to grow.
Cities will need partners to help them provide these building blocks for the future. The public sector cannot address these crucial needs alone, and overall official development assistance barely totals three percent of this amount. Cities should begin looking toward innovative financing options and to the private sector.
As the world urbanizes rapidly, – it is estimated that only 1.5% of the world’s land is home to about half of global production.
Such economic concentration is a built-in feature of human settlement development and a key driver of growth. However, while some countries have succeeded in spreading economic benefits to most of their citizens, many other countries have not.
Especially outside the economic centers that concentrate production, there are “lagging areas” with persistent disparities in living standards and a lack of access to basic services and economic opportunities.
Over one billion people live in underserved slums with many disparities from the rest of the city in terms of access to infrastructure and services, tenure security, and vulnerability to disaster risk. A further one billion people live in underdeveloped areas with few job opportunities and public services.
How can countries address the division between the leading and lagging regions?

Hurricanes Harvey, Irma, and Maria that pounded coastal United States and the Caribbean; the severe drought that struck Somalia; forest fires that are ravaging through southern California… Hard to miss were the natural disasters that displaced – even killed – individuals and families.
There were also the “manmade” disasters – conflicts that erupted or lasted in many parts of the world continued to force men, women, and children out of their homes and homelands.
Yet, turning to the bright side,
Just a couple of weeks ago, for example, global and local leaders gathered at the One Planet Summit in Paris to firm up their commitment – and ramp up action – to maximize climate finance for a low-carbon, disaster-resilient future.
At the World Bank, our teams working on social development, urban development, disaster risk management, and land issues have endeavored with countries and cities worldwide throughout the year to achieve a common goal: building inclusive, resilient, and sustainable cities and communities for all.

#1: Africa’s Cities: Opening Doors to the World
Released in February 2017, our report on cities in Africa notes that, to grow economically as they are growing in size, Africa’s cities must open their doors and connect to the world. Improving conditions for people and businesses in African cities is the key to accelerating economic growth, adding jobs, and improving city competitiveness. Two more reports released in 2017 also shined a light on inclusive urban growth in East Asia and the Pacific and in Europe and Central Asia respectively.
